Y '0 all whom it may concern:

Be it known that 1, ANDREW A. Molit TYR a. citizen of the UnitedStates, residing v in the county ofCamden and State of New Jersey,.have invented certain new and useful Improvements in Heel Breasting Mechanism, of which the followin; is aspecification.

at Camden,

This invention relates, heel breasting mechanism and has more particular relation to the providin'pgof a cut ting-block of new and novel design foruse in conjunction."ftherewithl As at present practised, R the so-called leather Louis. heel of ladies shoes is built up of sup erimposed layers, pieces or strips of leather of substantially the samesize. It

necessaryto cutor trim theinner edges of these piecesfor strips in such super1m-' posed relation, 1n order to obtain the proper;

graceful curverequired fora Louis heel. For this purpose, a heel breasting mechanism is employed the reciprocating cutter or knife of which in itsforward movement impinges against a solid, wooden cuttingblock. Much dissatisfaction results from this method because ofthe following, facts:

perfect heel is provided as a result of pense, both to cost of block I p time in making the necessary ehangejof' First, a wood outting block frequently," and in some instances ina single movement of the knife or cutter, splinters or crushes to such extentas to render the blockuseless for'desired-purposes and the sp'lintering or crushing-of salidblock." Second, a wood cutting-block requires frequent changes and isan item of considerable eX- andloss of block. Third, the reciprocating cutter or knife during its forward movement 5m pinges against a cutting-block thus drilling" the cutter orlrnife edge, with the result that frequent changes of cutters or knives for rte-sharpening purposes is required. This procedure alsoconsumes valuable time and is an added expense. I i

The principal object of the present in- 'vention is to overcome the above reciteddisadvantageousfeatures and provide a rigid, shock-resisting cutting-blockhaving formed in the workingface thereof a cutter or knife edge receiving; opening designed so that the suttinp; offs. cutter orilmife ear not broadly stated, to

at the same time an inn.

contact with the'ledges of said opening. Other andfurtherflobiects of the present invention residein theproviding of a more efiicient, rapidv and econoinical heel breasting mechanism than is now in general use.

With these and other objects in view, the invention consists of the improvements hereina'fter "described andfinally claimed.

The nature, characteristic features and scopeofthe invention will be more fully understood from the following description taken in connectionwith the accompanying drawing forming part hereof and in which; Figure 1, is a view iii-front elevation, of a heelbreasting mechanism, equipped with a cutting-block embodying the invention;

Fig. 2, is a view in'crosssection thereof; Fig. 3, is a fragmentary view in plan of the cutting-block and holder therefor; Fig. 4, is a front view ofFig. 3;

1 Fig. 5, isa perspective view of a cuttingblock before assembling, and

6, is a perspective view of form of *cuttingylolock.

For-the purpose of illustrating my inven-' tion, I have shown in the accompanying drawings two forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, althoughit is to be understood that the various instrumena modified t'alities ofwhich my invention consists can arranged and organized and be variously that'myinventlon is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described. r

Referring to the drawings and more particularly to Figs. 1 and 2, there is illuswith respect to the beam 1 is a heeldivided'into a shoe clamp 15,0f angular cross-section, see Fig. 2.

atively disposed with respect to heehclamp 15. Motion is imparted to said shaft by means of an eccentric and cam-follower connection 19, operable from amain driving shaft 20, through the intervention of bevel gearing-.21. Releasable stop-mechanism 22 of any desired form is present to permit a complete reciprocation of the .cut-

- ter or knifelS for each two revolutions of driving shaft v2O. Carried by standard 111, opposite the :knife'or cutter just described and adjacent the heel-clamp 15, is a holder 22, for supporting in fixed position acne tingablock' 23. As shown the holder if desired may be adjustedendwise as at 2&1, or maybe moved around a pivot connection 25. The. cutting. block 28, disposed in the path of travel .ofthe .endwise movable knife or cutter 18, and receives the shock or impact of the throw of the eccentric when the knife or cutter passes through ,a heel being breasted. The cutting-block I have designed isadmiraib ly fitted to meet this condition in that I employ a member of rigid, shock-resisting material, preferably metal, and slot, groove or otherwise form in the working face of the block an opening to receive the cuttin -,edge of the knife or cutter at the end .0 its forward stroke. The slot or groove is ample to re,- ceive said cutting-edge without the latter contacting in any way with the block. As shown in Figs. 3, 4 and 5, this cuttingblock :is of twosections 26 and 27. These sections are so formed and proportioned that when assembled within the holder 22, and clamped thereto, as by bolts 28 there is disposed betweenthe two sections a slot or groove 29. Obviously, depending upon the particularshape .of cutter or knife .used, the specific formation of the adjacen t faces oft'hese sections vary inmanufacture. In

the present instance, the cutter is substanearl iJ-shaped so that asubstantially J-shapednopening between the two sections is'required. The general configuration of the cutting-block, however, is substantially rectangular with a generally curved, working face 30, and an offset 31, for one Side.

The working face 30 of the cube-like cutting block is :curved convex'ly to conform to the contour of the side ofa shoe heel so that an efficient side support is afforded v The rear. portion .of the cuttingb lock abuts against the front wall 32, of

the holder 22, and the offset 31, abuts against the front edge 83, of the holder 22. The end thrusts, shocks or impacts of the cutter or knife as it trims a shoe-heel are referred by the shoe to the shockresistingcutting block of the invention and as the block rigidly clamped as aforesaid within the holder, there is no give to the cutting-block so that a clean cut of the cutter or knife is assured.

Fig. 6, the cutting-block is formed of a one-piece casting 34, the working face of which is provided with a slot or groove 35.

The above described mechanism is particularly designed for the breasting of leather Louis heels for ladies shoes. These heels are built up of superimposed pieces or strips of leather of the same relative size.v At the proper time in the manufacture of a shoe, the shoe which has a last fitted therein is placed upon the shoe- .support 16, in the position shown in Fig. 2,

and the support is moved inwardly until the heel of the shoe abuts against the heel-clamp 15. The latter is then screwed down upon the heel, It is to be understoodin this connection that ,so positioned the shoe itself abuts against the curved or working face 30, of the cuttingablock23. In operation one for Ward movement of the cutter or knife shapes the inner surface, .of the heel by cutting away the edges ,of the various projecting strips. I i It will new be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the in.-

vention andthe above description and while i I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention as claimed or sacrificing any of its dv n ag s What I claim is: r I 1, A mechanism of the character state embracing in combination a fixed substantially cube-like cutting block of rigid shock resisting material, the working face of which is convexly curved .and conforms in contour to the side of a heel, said face having formed therein a knife edge receiving opening, a knife movable across the breast of a heel, the cutting edge vof which is accomsaid face having formed therein a knifethe combined sections being convexed to con edge receiving opening form to the contour of the side of a heel. 10 3.
